Lead sulphide; the principal ore of lead. It is of a bluish gray color and metallic luster, and is cubic in crystallization and cleavage.
Lead sulphide used as a glaze, for example on English medieval earthenware pots.
(der) Bleiglanz, (der) Galenit Lead sulfide (PbS); important lead ore, called argentiferous if Silver is built into the crystal structure. Therefore can also be an important Silver ore.
A grayish mineral ore, composed chiefly of lead sulfate (PbS), from which metallic lead is extracted. The Route 66 town of Galena, Kansas owes its name to this local resource.
lead sulfide (PbS). Technical grades (specific gravity about 7) are used for increasing the density of drilling fluids to points impractical or impossible with barite.
This is the word the Greeks used for a kind of lead ore. To the Romans, galena was what was left after the lead was melted out of the ore. Galena is the ore from which we get most of our lead.
Lead sulfide, the most common ore mineral of lead.
soft blue-gray mineral; lead sulfide; a major source of lead
A bluish-gray to lead-gray sulfide mineral, PbS, with a specific gravity of 7.4-7.6. It has a shiny metallic luster, exhibits highly perfect cubic cleavage, and is relatively soft and very heavy. Galena is the most important ore of lead and in hydrothermal environments is commonly associated with zinc and silver mineralization.
The major ore mineral for lead (PbS).
A bluish-gray to lead-gray mineral. It frequently contains included silver minerals. It has a shiny metallic luster, exhibits highly perfect cubic cleavage, and is relatively soft and very heavy. Galena is the most important ore of lead and one of the most important sources of silver.
Naturally occurring lead sulphide; frequently associated with silver. When pure, galena contains 86% lead.
A lustrous, blue-gray lead ore mineral, usually crystal lised in cubes. Galena crystal s were commonly used in ‘ crystal' radio sets.
A soft, heavy bluish-grey mineral, chemical formula PbS (lead sulphide). Galena is the most important ore of lead and one of the most important sources of silver.
Lead sulphide, the most common ore mineral of lead.
native lead sulfide, PbS, or lead or silver ore, or the slag remaining after refining lead.
Lead ore geode- a rough, round-like stone that has crystals inside gold a yellow high density metallic element resistant to chemical reaction, occurring naturally in quartz veins and gravel granite a granular crystalline igneous rock of quartz, mica, feldspar etc...used for building gypsum a hydrated form of calcium sulfate, occurring naturally and used to make plaster of Paris, and in the building industry
An ore of lead sulphide used as a glaze.
a metallic, gray mineral containing lead and sulfur. It is the most common lead mineral and the chief source of lead. [AHDOS
Galena is the natural mineral form of lead sulfide. It is the most important lead ore mineral.
